Two stars 16 light-years away are barely resolved by a 62-cm (mirror diameter) telescope. How far apart are the stars? Assume λ=560nm and that the resolution is limited by diffraction.
Added by Albert F.
Step 1
We need to find the angular resolution of the telescope, which is given by the formula: θ = 1.22 λ/D where θ is the angular resolution in radians, λ is the wavelength of light, and D is the diameter of the telescope mirror. Plugging in the values, we get: θ = Show more…
